As I am new to this type of vehicle, I was wondering just how rough a ride to expect. I have 245 70 R19.5 Michelin XRV tires all at about 86-88 psi. The ride is really rough over any road bumps, joints, etc. Really shakes everything. Is this normal? Tires too full? Shocks? On a smooth road the ride is smooth.

A lot of truck stops have scales. They will weigh each axle ( all four corners is best but a little more difficult to find a place ). Then you refer to a tire chart for those weights and adjust pressures. This will help with the ride.

As a suggestion: Some landfills (garbage dumps in the good old days) have scales and you might be able to use them. In Oregon you can use the highway scales but I don't know if you can do that in you area.

I am running my Goodyear tires, the same size as yours, at 80lbs. I think yours are a little high and it will make a difference if you can lower the pressure a little. Also, Koni's are a good shock and would help also. Good luck!

Went to the truck stop and weighed it yesterday. I looked up the Michelin recommended tire pressures and at the weight I am at even fudging up hundreds of pounds for "stuff" I can lower to the minimum they list at 80 lbs. Hope it helps. If not I guess I should consider new shocks.
